Solar panels for the Anker SOLIX S2000

Written by Ian Schneider·Solar & Off-Grid Tester

The S2000 takes solar through one XT60i socket, a variant of the yellow two-pin XT60 plug, and Anker's spec table files it under MPPT Input. MPPT is the maximum power point tracker, the circuit that holds a panel at the voltage where it gives the most. The socket is rated for 11 to 60 volts and 400 W. Thirty-one of the forty-one panels we track publish an open-circuit voltage, Voc on the label, what a panel reads in sun with its leads unplugged. All thirty-one sit under 60. The other ten have no Voc in our catalogue, four of them Anker's own.

The 400 W comes with a condition. Anker gives the socket two current limits, 8.2 amps below 28 volts and 12.5 amps above, and prints the 400 W beside the second. The rigid panels and the big folding ones read above 28 on the label, so they get the whole socket.

One panel fills it alone: Renogy's 590 W rigid bifacial, at 58.4 pounds. Everything else gets there as a set. Two of EcoFlow's 400 W folders do it, and so do two of Anker's own 440 W rigid panels. With the socket full, the 2009.6 Wh battery is done in about five hours of good sun. One 200 W folding panel on its own gives about 144 W and needs about fourteen hours. At the cabin I'd carry two folders out on Saturday morning and not look at the screen until Sunday.

The door

Every panel we track, lined up at the SOLIX S2000's solar input

Every panel we track, standing in a line by its Voc, the open-circuit figure from the label. The black line is 60 V. Nothing in the row reaches it.

The pale cap on each bar is the extra voltage a cold morning adds, about 10% at -10 °C. On my deck in January a panel reads taller than its label says. Here that costs nobody anything. The tallest panel we track, Renogy's 590 W, reads 52.63 on the label and stays under 60 with the cap on.

A day on solar

How long the SOLIX S2000 takes to charge on solar

Anker's product page calls it Fastest Solar Recharging. Five hours is the number behind the words, with the socket full, and thirteen sets of panels get it there. One 200 W folding panel on its own gives about 144 W and needs about fourteen hours. One 100 W panel gives about 72 W and needs about twenty-eight, which is not a weekend.

A good day brings 3 to 6 hours of sun that strong. Two EcoFlow 400 W folders fill the battery in one of them. The single 200 W panel needs several. Where you live and the month decide how many such days you get. The system builder has the count for your state.

Every panel that fits

Solar panels compatible with the SOLIX S2000

Thirty-one fit. Each row gives the cable it needs, what one panel delivers in good sun, and the best set the S2000 will take. None of the thirty-one plugs in without a lead. Most want an MC4-to-XT60i cable, MC4 being the weatherproof snap-together plug on the back of most panels. The What's in the Box list on Anker's S2000 page belongs to the C1000 Gen 2, so whether a solar lead ships with the S2000 is a question for the carton.

Own a panel that isn't in the line-up?

Type its voltage into the door chart above for the height test, then put the rest of the label into the panel checker, already set to the SOLIX S2000, for current and plug too. Or build the whole system to see how it keeps up where you live.

The plain answers

How long does the SOLIX S2000 take to charge on solar?

One 100 W panel delivers about 72 W in good sun and refills the 2009.6 Wh battery from empty in about 27.9 hours.

One 200 W panel delivers about 144 W in good sun and refills the 2009.6 Wh battery from empty in about 14 hours.

At its 400 W solar limit it refills in about 5 hours. More panel watts than that won't charge it any faster.

A day gives three to six hours of sun that good, depending on season and place, so one 100 W panel takes 5 to 10 days to fill it. The system builder works it out for your state and month.

What adapter does the SOLIX S2000 need for solar?

Every panel we track needs a cable to reach its XT60i input.

The cables they need: MC4 to XT60i (11 panels), DC8020 to XT60i (4 panels), Anderson to XT60i (3 panels), DC5521 to XT60i (2 panels) and XT60 to XT60i (1 panel).

10 panels don't have a named plug from their maker, so check the lead before you buy a cable.

Can you use non-Anker solar panels with the SOLIX S2000?

Yes. What decides it is the panel's voltage and plug, not the brand. 31 panels from Renogy, Jackery, Anker SOLIX, EcoFlow, BLUETTI, Eco-Worthy and Rich Solar work with it, as long as the panel stays under 60 V on a cold morning and starts above 11 V.

The strongest single panels here are the Renogy 590W N-Type Bifacial (400 W delivered) and the Jackery SolarSaga 500 X (360 W delivered).

Can you connect two solar panels to the SOLIX S2000?

Yes, joined into one input with a series or parallel cable.

Don't wire two BLUETTI PV100 FX Flexible panels in series: together they would pass its 60 V limit. Parallel them instead.

Past 400 W delivered, more panels only help on cloudy days.

What is the SOLIX S2000's solar input?

XT60i Input Port (spec row: "MPPT Input"): 11–60 V, up to 12.5 A, 400 W.

Input limits from Anker's documents, checked 2026-09-18 (source). Delivered watts assume 72% of the panel's rating in good sun.
